Some users told me that they could not log into the system. They said they kept getting the login window again and again without any error message. At first I was sure they were simply not allowing cookies but than came Manuel Lemos and taught me something new about cookies and Y2K. It seems that different browsers see the expiration date in the cookie differently. This "problem" applies to any server side language, says Zeev Suraski, because it's a client- side problem. Navigator 3.x doesn't understand 4 digit years. On the other hand, it properly understands 00 through 69 as 2000 through 2069, so it works ok even today with 2 digit years. The problem is that some browsers today no longer understand 2 digit years, so you can't really win - if you use 4 digit years Navigator 3.x wont work, and if you use 2 digit years some other browsers wont work. There are two ways to overcome this: 1. Set your y2k_compliance in your php.ini to "on" and then older browsers might have a problem with the 4 digits (NC 3.x will probably not work) but hey, it's time to upgrade Statistics on WeberDev shows the percentage of NC 3.x users on 0.43% so I guess, for the best of everyone those 0.43% upgrade their browsers. 2. The second solution offered by Manuel Lemos was to fallback to not set the cookie expiry date (volatile cookies). In any case, I thought this was important enough to make an example of.
